How much water to add to make a 500 dilution?
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
What is the molar solution?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
What does dilution and concentration mean?
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
How much grams of kmno4 to prepare 1000 ppm solution?
To prepare a 1000 ppm (parts per million) solution of KMnO4 (potassium permanganate), you need 1000 mg of KMnO4 per liter of solution. Since 1 gram equals 1000 mg, you would need 1 gram of KMnO4 dissolved in enough water to make a final volume of 1 liter. Therefore, to prepare a 1000 ppm solution, dissolve 1 gram of KMnO4 in 1 liter of water.
How much sodium chloride must be added to one liter of water to make normal saline?
To make normal saline, you would need to add 9 grams of sodium chloride to one liter of water. This is equivalent to approximately 0.9% saline solution.
You want 1 liter of 0.1 M NaCl and you have 4 M stock solution How much of the 4 M solution and how much dH2O will you measure out for this dilution?
To make 1 liter of 0.1 M NaCl solution, you will need 25 ml of the 4 M NaCl stock solution and 975 ml of water. This will give you the desired concentration of 0.1 M NaCl in a total volume of 1 liter.
How much water to add to make a 500 dilution?
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
How much water must be added to 1 liter of a 5 percent saline solution to get a 2 percent saline solution?
At dilution always true:Volume*concentration = amount of solute (= constant, not changing)So 1 (litre) * 5 (%) => 5
How do you prepare 1.5 mol per liter of hcl in solution?
By dilution, but this depends totally on:How much litres you want to have. (suppose V1 Litre)The concentration of the UNdiluted (more concentrated) HCl you have to start with. (suppose M2 mol/L HCl)Then, with V1 * M1 = V2 * M2, you can calculate V2, which is the amount of undiluted HCl solution (in Litre):V2 = [V1 * 1.5] / M2
What is the molar solution?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
How much calcium chloride should be added to a liter of water to produce a saturated solution?
This is from the website linked to the left of this answer under Web Links:Solubility in water, g/100 ml at 20°C: 74.5Therefore, in 1 liter, 745.0 grams of CaCl2 will dissolve to make a saturated solution.
What is Molar Solutions?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
Suppose 1 liter of water with conductivity 10 microS per cm and 1 liter of water with conductivity 20 microS per cm are mixed together then how much will be the conductivity of the net solution?
13,2
A chemist wants to make a 10 solution of fertilizer. how much water and how much of a 30 solution should the chemist mix to get 30 L of a 10 solution?
30 liters of a 10 % solution of fertilizer has .1(30) = 3 liters of fertilizer 1 liter of 30% solution has .3 liter of fertilizer 10 liters of 30% solution has 3 liters of fertilizer so, the chemist needs 10 liters of the 30% solution and 20 liters of water to make 30 liters of a 10% solution.
How much of a 50 percent solution should be added to 1 liter to make a 25 percent solution?
Mix this 50% solution in equal quantities with water(?) to halve it's strength. So use 1 litre of the 50% solution and 1 litre of water of that's what you are diluting it with.
How much sea salt do I add to tap water to make a salt water solution that emulates sea water.?
Seawater has a salinity of arround 3.5 percent. 1 liter is 1000 cubic centimeters needs 35 gram of salt so get this solution.
What does dilution and concentration mean?
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
